@freddy333. I just pulled this from the web:
"I suspect that your Colt does do it, just quieter. It's the sound of the ratcheting mechanism in the winding mechanism. To unscrew the crown you have to turn it in the opposite direction to winding the watch and so the teeth 'slip' rather than engage and that's what you are hearing." and
"Sounds like everything is normal! What you are hearing is the winding pinion. Rest easy. Roff is correct. Enjoy the watch!"
This was re a Breitling chronomnat manual wind. Could this be what i am hearing?
